KR100427017B1 - Apparatus for selectively controlling the lateral oscillation motion of a warp in a loom - Google Patents

Abstract

The proposed apparatus for selective control of the lateral oscillatory motion of the radiation 4 comprises sinkers 6 which are operated in a vibrating fashion and which are made to match the radiation carriers 22a, 22b. In order to be able to individually control the slopes 4 to be moved in the transverse direction, the individual carriers are fitted to the actuator 60 which moves the carrier from the initial position where it can not pick up the radiation to the radiation pick-up position. This simplifies picking up the radiation and controlling lateral movement.

Description

Apparatus for selectively controlling the lateral oscillation motion of a warp in a loom

Devices of the type mentioned above are well known. For example, such devices are used in the production of patterned materials to selectively control the inclination of a shaft loom or a Jacquard loom. Each slope is guided through the closing eyes of the heddle and directly raised or lowered using the shaft of the shaft loom or a vertical harness of the Jacquard loom. Such devices are alternatively described in U.S. Pat. 4,936,352, EP-B 0 421 370, EP-A 0 302 798, EP-A 0 534 523 and DE-C 4 023 512.

One disadvantage of this type of selection and movement of individual warp yarns is that they have a lot of electrical and mechanical costs that require a considerably large space in a shaft or a Jacquard loom that is close to or above the cost of the loom, Is high. The more individual threads you have to control, the greater the cost of solving them. Further and further drawbacks of the present technical apparatus are that, except for the technique of jacquard or shaft looms, all warps must be guided respectively through the closing eyes of the looms. There are considerable human or mechanical costs involved in pulling the slope. By the guidance in the eyes of the heel, the degree of freedom of the incline is reduced, and therefore, the incline is free to move only in the direction of the cannon. It must be compensated for the expensive control and manipulation by direct elements such as shafts as well as indirect elements such as shafts, vertical transport mechanisms, Jacquard plates, magnets, etc., where the elements are individually grouped in a Jacquard loom or grouped in a shaft loom Other movements of the slope are temporarily performed.

USP NO. No. 5,261,464 discloses an apparatus consisting of open-eye sleeves in a sinker that moves up and down. This device, however, has other drawbacks. The design of the opening is used only to pull out the tilting when the loom is still, keeping the connections of the yarns disconnected during weaving. Also, only a few warp thicknesses can be accepted by the guiding element based on the design. The manipulation of the heels is accompanied by considerable mechanical costs.

The present invention relates to an apparatus for selectively controlling the transverse vibration motion of a warp in a loom according to the preamble of claim 1.

It is an object of the present invention to provide a device of this type designed to allow direct control of the tilt, which replaces the previously closed tapered opening in the heel and avoids direct elements such as in a shaft or a Jacquard loom, To select individual slopes requiring a space of < RTI ID = 0.0 >

This object is achieved by the characteristic feature of claim 1 of the present invention. Thus, the carrier only grasps the tilt when the actuator operates the control means such that the tilt is attracted by the corresponding carrier. Otherwise the slope is free. On one side, the inclination can be individually captured and controlled in the simplest manner, on the back side, if it is substantially easy to incline through the device. Thus, in the case of control of the warp, and correspondingly in the case of a loom, the likelihood of making a pattern in the fabricated material is substantially improved.

This device is suitable for the widest possible applications. So, for example, it can be used in inclined conveyors to selectively pick up various color and quality gradients.

This device has additional practical advantages when used in combination with looms in particular. Through the integration of the selection mechanism into the sinker, a number of useful mechanical elements for controlling and deflecting slopes are created, such as in a shaft loom, a Jacquard loom and a loom loom. For example, if sinkers are connected to the loom's axes, they no longer need to be sent irregularly according to the material pattern. Instead, they can all be sent simultaneously, for example, with sinusoidal action, so they can be a substantially simpler and more robust design that avoids cost and increases the reliability of the operation. By avoiding the indirect control and manipulation elements between the selection device and the controlled ramps, the required forces are reduced, which minimizes the demands on the device and energy considerably. The slope can no longer be threaded through the jaws and can move freely along the sinkers in the unconnected state. During operation, as well as during operation of the loom, they can be connected and short-circuited, It creates advantages when it comes to.

Beneficial embodiments of the device are described in claims 2 to 16.

The present apparatus can be implemented in various forms. Thus, the carriers can be fixedly connected to the sinkers, where control means operated by the actuators are used to guide the slopes to the carrier as required to catch them with the sinkers. A third preferred embodiment of this type is described in claim 2. Yet another basic embodiment of the present invention is that no oblique capture occurs. From the initial position, to move the carriers themselves to a transport position where the tilt is deflected by means of the sinker, using the actuator means. Beneficial modifications of embodiments of the second type of control are described in claims 3 and 4.

The sinker's carrier can be manipulated in both directions of the sinker movement if necessary. For this purpose, the carrier takes the form of a fork, in which the fork opening is positioned transverse to the direction of movement of the sinker. While the sinker is constituted by a second carrier operable in the other direction of movement, or the carrier used during the other direction of movement is connected to an additional sinker. There are many variations in the placement and location of the carriers. Thus, the carriers may be hook-shaped or may include a V-shaped groove to securely hold the slope at least. It is also an advantage, in particular, to place the carrier at the end of the curved control tongue. The carrier can be formed, for example, through a deformation of the control post or through a separator provided on the control tongue. The function of the control point can also be deduced from the special form of the sinker already mentioned above. For this purpose, a further embodiment of the controlled element is described in claim 6. The certainty of gripping is improved in accordance with the embodiment of Claim 7, and a further embodiment thereof is developed in Claim 8.

In particular according to claim 9, wherein the slope selected by the sinker is separated from the other slopes by means of a separating sinker. The latter can also limit the control needle and the deflection of another moveable control means. Particularly advantageous arrangements and embodiments of sinkers and separating sinkers are described in claim 10.

The actuator is advantageously electrically controlled in accordance with claim 11. The actuator may include various components such as piezoelectric elements, magnetic coils, permanent magnets, memory alloys, bi-metal strips, and the like. It is essential that the actuator be electrically controlled. In particular, actuators of minimum energy consumption, such as piezoelectric elements, for example, are advantageous. It is also advantageous at least to have an arrangement according to one of claims 12 to 15, wherein the elements for controlling, regulating and monitoring the sinkers and the control actuator itself are integrated automatically in the sinkers. Interfaces or wireless connections within the base region of the sinker, such as optical connections, and interlayers integrated in or on the sinker, may be used to monitor biased states and functionality as well as electrically Control and accordingly adjust it.

The sinkers can be removed from the carriers, respectively, and can be installed again, for example, for repair purposes. Bundling a plurality of sinkers together into one group can be practically beneficial in setting up, for example exchanging, sinkers.

Within the base region, the sinkers and separating sinkers are connected together using spacing pieces of varying thickness, so that their separation corresponds to the required thickness of the inclination. The elements necessary for controlling the group can be distributed on at least one of the sinkers themselves or in the base region of the group, or outside thereof, i. E., Away from the sinker and base region.

A beneficial form is described in claim 16, wherein the upper end of the sinker protrudes from one side to the opposite direction to an exact degree, that is to say corresponding to the separation in the base region, and on the other side they are manually and / Are separated from each other at the same time to be recognized and selected through automatic tilt sensing devices.

The sinkers are connected to an existing control device that controls a plurality of sinkers so that a particular pattern can be created. One such control device may comprise a computer or be connected to a computer and may be connected to the input of any pattern (e.g., figure) using a scanner or a CAD-program and to the manipulation variables of the loom 0.0 > tilt < / RTI > The highest and lowest points of the weaving shed are thus converted into corresponding control signals for the carriers located on the sinkers so that the desired weave pattern is created.

1 is an apparatus for controlling a warp yarn in a loom, for example, for selectively controlling the lateral oscillation motion of warp yarns.

Figure 1 shows a right angle bar 2 in which a warp yarn 4 is fed from the junggongbong 2 and the warp yarns 4 are fed from a rest position, In the vertical direction. A weaving blade or reed 14 serves to place and press the warp 15 of the fabric inserted into the weaving area 12 at one end 16 of the product. The resulting squeezed material 18 is directed onto the product beam 20. The individual sinkers 6, 6a, 6b comprise carriers 22, each of which can be operated from an initial position in which the tilt can not be captured to an inclined capturing position using the actuator and control means. For operation of the actuators described in more detail below, a control device 24 is installed and connected to the sinkers 6 using leads 26, respectively.

Each of the sinkers includes two carriers 22a and 22b each of which is inclined from the intermediate position 10 to the upper region 28 or the lower region 30 to form the weave region 12 4) in one direction only during the movement of the sinker. On the other hand, it is possible to use two sinkers 6a, 6b located on two supports 8a, 8b for deflecting one slope 4 from the intermediate position 10. [ Thus, one sinker 6a can deflect one slope 4 only into the upper region 28 while the second sinker 6b deflects the slope to the lower region for the next wigging cycle. In this way, the operation of the sinkers with double rhythm is possible with carriers operating at 1/2 the number of times. The structure of the loom, as well as the drive for the axially supported supports, is well known and, in view of this, the above cited patents, in particular EPA 0 534 523, are mentioned.

The individual embodiments and arrangements of sinkers are described in connection with Figs. 2-6. Fig. 2 shows how a plurality of sinkers 6 are arranged in special groups by being heated on a support 8. Each sinker 6 has a separating sinker 32 positioned on both sides with spacing determined by a separating element in the form of a spacer 34 arranged thermally on the supports 8 between the sinkers. On both sides of the support, the end pieces 36 are installed and secured to fix the sinkers 6, 32 and the spacers 34 to their respective positions on the support 8. The end fragments serve as part of the energy supply and / or data exchange in an unspecified manner. The sinkers at the ends of the sinkers 6 and the separation sinkers 32 facing away from the support 8 are provided with additional spacers 38 which are formed using bows, for example, in the housing of the sinkers . These spacers strike spacers located opposite the sinkers and additionally form a guiding surface 39 for the inclined path. The separating sinkers 32 serve as joints for separating the warp yarns 4a which should not be processed by the individual sinkers 6 on the one hand for the operated carriers 22a and 22b do. The processing of the plurality of warps can also be divided among the various sinker sets indicated by sinker sets I and II in FIG. One such twisting of the sinkers on the support plane located on the other side of the support plane causes the slope density to increase.

Figures 4-6 show the individual structures of the sinkers that may be required for use in Figures 1-3. The sinker is comprised of a housing 42 formed of two shells 42a, 42b welded together at an end 44 thereof. The housing consists of a foot 46 with two legs 48 clamped around the support 8 so that the sinker can be slid onto the support stand or onto the support stand. The sinker, on the other hand, can also be connected to the support in many different ways, for example using screws, adhesives, and the like. The sinker also includes a head portion 50 to which individual slopes are guided upwardly. A pair of carriers 22a, 22b operable in two directions of the movement of the sinker are arranged on both sides between the lower foot 46 and the head part 50, respectively. The carriers are fixed at the end of the control means, which is configured as a control element in the form of a tongue 52. The pins are fixed with the adhesive and / or pins 58 to the fixing portions 54 in the reinforcing pads 56 in the housing 42 with others. The actuator 60 is fixed to a control point which can be manufactured from various materials, preferably spring steel. The actuator may be formed, for example, on a piezoelectric element. The actuator 60 is activated using a conductive passage 64 which is arranged on the intermediate layer 62. As soon as the actuator 60 receives current through the conductive passageway 64 a bending of the control stem 52 is provided whereby a hooked carrier 22b located at an initial position in the housing of the sinker is received within the housing 42 Through the opening 66 to the catch position shown in Figures 2 to 6 and catches the warp 4 by the upward or downward movement of the sinker within this position.

The actuators 60 for the carriers 22a, 22b on both sides of the sinker are connected through a conductive path 64 to a circuit 68, which is an integrated circuit, for example referred to as an IC, And is installed in the housing. The circuit is used, for example, for control and control of the actuator 60. The circuit is connected to the contacts 72 in the lower end 46 through a plurality of leads 70, which are used, for example, for energy supply and / or data transmission. The contacts 72 are connected to additional contacts 74 in the support 8 which are connected to the external control device 24 via a lead 26. The control device controls the sinkers (22a, 22b) of the sinkers and / or any patterned sinkers so that the warp yarns (4) are captured by the sinkers according to the weave pattern to be provided.

In correspondence with the individual arrangement of the sinkers 6 and the separation sinkers 32 on the support 8 according to Fig. 2, Fig. 7 shows that a plurality of such sinkers 6c and separation sinkers 32a Grouped and fixed or fixed within the common pedestal 76 by, for example, an adhesive. The pedestal 76 may then be secured to the support 8 in the manner already described above. The sinkers 6c are in this case connected to the common circuit 68a using the leads 64a for all the sinkers in the group. A conductor 70a for providing energy or for providing data transfer to the circuit 68a is here passed in parallel to the support 8. The leads used for data movement may be formed as channels 70b for the transmission of optical signals that are tied to the leads of neighboring pedestals in a manner not shown. The leads 70a and / or channels 70b are connected directly or indirectly to the transfer device 77 located at one end of the support for energy / or data transfer to control the sinkers. A battery for energy supply can be placed in the pedestal instead of the energy supplied to the lead from the outside.

Figures 8 and 9 show a cross-sectional view of an additional sinker 6d to be designed as a membrane 78, the control means being, for example, part of the housing 82. [ The membrane 78 has an actuator 60a. Membrane 78 is moved out of the initial position within the interior of housing 82 using actuator 60a and inwardly as desired to a captured position where the membranes protrude from the housing.

10 and 11 show further modifications of the cross-sectional sinkers 6e. The control means is formed as deflection means and consists of deflection points 84a, 84b which are arranged with actuators 60b in pairs on each side of the housing 86. The deflection points in the base regions conceal the carriers 22d that are fixedly arranged in the housing 86 of the sinker 6e. The free end 88a of the deflection cen 84a protrudes into the sliding passage of the tilt 4 and the free end 88b of the other associated deflection cen 84b is pointed and tilted inward 4 is guided to the carrier 22d. In the initial position, both deflecting tips 84a and 84b are pointed inwardly and do not tilt.
